nano ultrasonic sensors

With a housing length of only 55 mm

nano sensors with switching outputs are the smallest ultrasonic sensors inside the M12 threaded sleeve on the market. Analogue sensors are 60 mm long. nano has a 4-pole M12 circular plug and are taught via pin 2.

For the nano sensor family

there are 2 output stages and 2 measuring ranges available:

	1 Push-Pull-switching output, in pnp or npn circuitry with IO-Link interface
	1 analogue output 4–20 mA or 0–10 V

The temperature compensation

of the sensors profits from a significant improvement. The sensors reach their operating point only 45 seconds after activation of the operating voltage. We now compensate for the influence of self-heating and installation conditions. This brings improved precision shortly after activation of the supply voltage and in running operation.

New! With the internal alignment assistance

the sensors with Push-Pull switching output can be optimally aligned to the object during installation.

The nano sensors with switched output have three operating modes:

• Single switching point
• Two-way reflective barrier
• Window mode

Teach-in of a single switching point

• Place object (1) to be detected at the desired distance
• Apply +U_B to pin 2 for about 3 seconds
• Then apply +U_B to pin 2 again for about 1 second

Teach-in of a switching point

Teach-in of a two-way reflective barrier

with a fixed mounted reflector.

• Apply +U_B to pin 2 for about 3 seconds
• Then apply +U_B to pin 2 again for about 10 second

Teach-in of a two-way reflective barrier

To set a window with two switching points

• Place object to the sensor-close window limit (1)
• Apply +U_B to pin 2 for about 3 seconds until both LEDs flash
• Then move the object to the sensor-distant window limit (2)
• Then apply +U_B to pin 2 again for about 1 second until LED2 extinguishes

For setting an analogue output

• initially position the object to be detected on the sensor-close window limit (1)
• Apply +U_B to pin 2 for about 3 seconds until both LEDs flash
• Move the object to the sensor-distant window limit (2)
• Then apply +U_B to pin 2 again for about 1 second

Teach-in of an analogue characteristic or of a window with two switching points

NCC/NOC

and rising/falling analoge characteristic can also be set via pin 2.

One green and one yellow LED

indicate the state of the output and support microsonic Teach-in.

IO-Link integrated

in version 1.1.2 for sensors with Push-Pull output. The nano-15/CF and nano-24/CF support the Smart Sensor Profile, which creates more transparency between IO-Link devices.
